Lessons about transporting Pillsbury dough

Ok, my wife and I sometimes eat some of the various Pillsbury dough products.  Today we learned that apparently there are ways you should not transport it home from the store.  Driving home from the store this evening we hear a noise from the back of the car.  Cathy thinks it’s a can of Pringles falling over, but I thought it sounded a lot like a loaf of bread popping.  Get home and check, and sure enough, it’s a loaf of bread.  As far as we can tell, the end of the can of bread was up against a pint of ice cream, and the shrinking from the cold caused just enough stress to cause the end of the can to pop.
